Liberal MSNBC host Chris Matthews said Thursday the accusation that President Trump directly colluded with Russia to interfere in the U.S. election "came apart" following former FBI Director James Comey's testimony in front of Congress.

In his written and spoken testimony on Thursday, Comey said that he never felt that Trump had tried to impede the FBI's investigation into Russia, even that the president had encouraged it and he suggested that former national security adviser Mike Flynn wasn't at the heart of the investigation.New rush for guns after attacks in LondonWatch Full Screen

"The assumption of the critics of the president, of his pursuers, you might say, is that somewhere along the line in the last year is the president had something to do with colluding with the Russians … to affect the election in some way," Matthews said on MSNBC, following the testimony.

"And yet what came apart this morning was that theory," Matthews said, listing two reasons why. First, he said Comey revealed that "Flynn wasn't central to the Russian investigation," and secondly, he said that kills the idea that Flynn might have been in a position to testify against Trump.
